Dragon Ball Z: Budokai Tenkaichi 3

I've sunk more hours into this game than any other fighting game I've played, so the score gets a massive nostalgia boost. It perfectly captures the style of the show in a way no other game has and boasts loads of content, fanservice and a supermassive roster. Unfortunately it's too accurate to the show to a fault, which mean it's also ridiculously broken and horribly unbalanced. Ultimately your enjoyment of this game will depend upon your enjoyment of DBZ overall.

It's a pretty good fanservice game since it includes pretty much every DBZ character you can think of (including Random Purple Alien Guy Who Worked For Frieza I Think) but I could never get the hang of the controls, and many of the characters felt basically the same to play.
